I am 53 years old and have recently developed tingling starting at the base of my skull and spreading upwards and forwards into my temples sometimes accompanied by pain in my temples. I also have sharp random pain at the base of my skull on both sides. A recent brain MRI with and without contrast revealed "scattered foci of increased FLAIR and T2 signal intensity measuring up to 3 - 4mm in the subcortical white matter of the right and left frontal posterior frontal lobes. There is no mass effect, edema, restricted diffusion, or enhancement seen post IV contrast injection. The findings would be concordant with non-specific gliosis. Differential includes microvascular disease, vasculitis, migraine encephalopathy and postinflammatory residuals. The pattern and distribution is not suggestive of demyelination. Can you please explain this in laymans terms?
